I see all of the stuff you need from me and he is not home rigth now, perhaps you can help me anyway...someone.. I'll give you the info I know about the tank and then the question. 75 gal tank, saltwater, been up and running 4 years, Iam not sure what kind of filtration but there are lots of pipes a water tank on the botton with white filtration sheets(1), a protein
skimmer. I do not know all the test numbers, nitriates,
ammonia, etc. I do know sality is 1.21 I think. There are 8 clowns, several damasels, lots of snails, different varieties, little hermit crabs, a gobbie, and here is the problem or question. We had 2 cleaner shrimp for about 1 month, today around 10am one had shed its skin. 8 hours later both of the shrimp are dead. Possibly a disease? any thoughts on this problem? thank you PaulaLovett
